Red Lake: A Guide to Romania's Landslide Lake in the Eastern Carpathians

Hidden in the Eastern Carpathians of Romania, Lacul Roșu—or Red Lake—is a natural wonder that looks almost surreal. The lake was formed in 1837 when a massive landslide blocked the Bicaz River, creating a natural dam. The forest that once stood in the valley was flooded, and today the bare trunks of dead spruce trees still rise from the water, giving the lake its distinctive, slightly eerie beauty. The name comes from the reddish sediment washed into the water from the surrounding iron-rich hillsides, though the lake itself often appears deep green or blue.

The lake lies in Harghita County, right at the foot of the Bicaz Gorge, one of Romania's most dramatic road passes. It is a popular stop for travellers driving the scenic DN12C route between Transylvania and Moldavia. The lake is small—about 8 hectares—but its setting is spectacular, surrounded by steep, forested slopes and limestone cliffs. A walking path circles the lake, offering constant views of the dead trunks and the mountains beyond. It is an easy stroll suitable for most visitors, taking about an hour at a gentle pace.

What to see and do

The main attraction is simply the lake itself. Photographers will want to capture the contrast between the silver-grey tree stumps and the deep green water, especially in the soft light of early morning or late afternoon. A small wooden bridge leads to a tiny island covered with pines, and row boats are available for hire on the shore for those who want to get closer to the trunks. For a wider view, follow the short trail up to the Suhardul Mic viewpoint, which looks down over the lake and the gorge entrance.

The lake is also a gateway to the Bicaz Gorge (Cheile Bicazului), a spectacular canyon with near-vertical limestone walls that tower hundreds of metres above the road. The gorge is part of the Cheile Bicazului–Hășmaș National Park, and several hiking trails branch off from the main road, leading to caves, lookouts and mountain pastures. Even if you only have a couple of hours, combining a walk around the lake with a short drive through the gorge makes for an unforgettable outing.

Practical tips

Red Lake is busiest in July and August, when the walking path can feel crowded and road traffic through the gorge is heavy. Late spring and early autumn are ideal, with fewer visitors and pleasant temperatures. The area sits at around 980 metres above sea level, so evenings can be cool even in summer—bring a light jacket. There is no entrance fee for the lake itself, and parking is available along the main road. Footwear with good grip is recommended for the trail to the viewpoint, as it can be slippery after rain.

If you are travelling by public transport, the nearest town is Gheorgheni, about 25 kilometres away. Regular buses run between Gheorgheni and Bicaz, passing the lake, and taxis can be hired from either town. The lake is also a stop on several organised tours of the Eastern Carpathians. Whether you come for an hour or spend a whole day exploring the surrounding trails, Red Lake offers a memorable glimpse of Romania's wild mountain landscapes.
